Property ZLevelFile: string
If this property isn't blank it specifies the name of a file with Z-level information from TeleAtlas files. Z-level is an integer from -9 to 9, which specifies the level of streets: One number for the start of the line and one number for the end of the line.
The file should be a standard text file with 2 numbers on every line: Z-level for start and end of line. The numbers should be separated by a white space. There should be the same number of lines as records in the base file.
When this property points to a valid filename, the information is used as part of function NWcreate and coordinates are adjusted slightly (10 cm = 4 in.) to prevent end-nodes at different Z-levels to have the same coordinates. Only if Z-level<>0, the modification is applied.
Filename is without path, but the file should be in the directory specified by property Directory.
